Would GIT submodules be a good idea?

What problem is splitting things into submodules supposed to solve?  The 
current Mercurial repository with everything in it is just 50 MB.  I 
suppose Git repositories take up more space, but assume that's not why 
you want to split things up?

If submodules are meant for the same use cases as SVN externals, they 
are primarily for automatically pulling in stuff that is separate 
because it is actually a separate project, probably maintained by 
someone else, or maybe just hosted elsewhere for some reason.  Not for 
splitting a project into parts.  Which is why I'm wondering what exactly 
you want to achieve here.
